We love electric cars. And we love Central Park. So you can imagine are delight when we discovered that next Tuesday evening, these very two things are coming together. On July 12, there will be a free screening of the film “Revenge of the Electric Car” (it’s not even in theaters yet!) at the Central Park bandshell, plus — and this is even more exciting — some of the most popular and advanced electric cars will be on display before the film. Visitors will have the chance to chat with industry experts before diving behind the scenes in Chris Paine’s documentary.
